Interesting list, thanks. Though the sites are nice, since they were the Top 10, I was expecting to see something out of the ordinary. But all the same I picked a couple of tips from their design/layout.

perhaps it skews the results my ignoring Number of Repeat Visits. i purchase from amazon perhaps 1 out of every 20 visits yet, according to this formula, you get the impression that i account for a 100% conversion (one unique customer / one unique visitor). in reality, they come closer to converting me 5% of the time.

Hi – I’m new to studying this stuff, so please excuse me if this is an amateurish question – how much of those conversion rates can be attributed purely to brand recognition and historic trust as opposed to on-site optimization and usability? I could make a note-for-note clone of Amazon.com (in theory) but I seriously doubt it would achieve a 16.4 conversion rate as an unknown.

So I just found the top 10 posts and have been reviewing them…and I might have missed this, but any ideas as to why the “flower” sites do so well? Is it a simple case of people like to send flowers or is there something more afoot?
